What a crummy medical plan and/or small town? Can you complain to the company owners, suggest they look around for a better plan? I'm in a good metropolitan area so never had that problem of too few practitioners (other than dermatologist who are too busy doing botox because it makes more money for them than serious skin problems).

I would see if you could find a psychiatrist (do you have hospitals nearby, especially a university teaching one?) and then see if you could ram them down the idiot insurance's throat?
